Yay fortuitous timing! :) It's not a trouble to change your name and the reader tag! (I wouldn't have offered if it would have been a problem.) For clarity when posting future podfics, either "Reader: sunspot" or mentioning in the post that you wish to be sunspot would be helpful.

There's about a dozen archivists; general_jinjur is in charge and aphelant is her second-in-command and then there's the rest of us. If you have an archive-related thing, you can always contact either of them (and they'll deal with it themselves or delegate it to someone else), or you can contact any other archivist (including me!) and we'll deal with it or pass it onto the relevant person. We kind of all really like the archive and making it useful to people and such-all, so we're happy to help!
